To give you (and others) a sense of the variability of Deer Creek in both volume of water and depth I have attached two graphs that cover the range of Feb 1, 2017 to December 31, 2017 so you can see what that looks like. Both the depth and volume can change relatively rapidly. As I mentioned either earlier on this thread or on the previous thread the depth gauge was 15 feet 9 inches at the peak in July of 2017. On the day the girls disappeared the water gauge showed a depth of 3.67 feet at 2:30pm. When we see the helicopter video which was around 3:00 to 3:30 pm on the 14th the depth was 3.22 feet.
That said there is much variability in the depth of the creek due the the contours of the creek bottom. But since water always seeks its level you can know that at all places along the creek the water was 5.4 inches deeper at 2:30 pm on the 13th.
Also, the higher the volume of water, the stronger the current.
All data and graphs for this water gauge can be found at the link below. Simply change the date range and it will generate new graphs. This link should show graphs for flow and depth for the period of 2/13/17 through 2/14/17.
